SCREW-NUT SECURER.

SPECIFICATION forming part of Letters Patent No. 793,553, dated June 27,1905.

Application filed December 27,1904:- Serial No. 238,446. A

To (all whom, it 7711141 concern:

Be it known that I, FRANs VAN TIIIEL, a subject of the Queen of theNetherlands, and a resident at Helmond,Veesstraat, Netherlands,haveinvented certain new and useful Improvements in Screw-Nut Securers,of which the following is a full, clear, and exact description.

The object of the invention in question is a nut-securer which offersadvantages, owing to its simple construction.

Figure 1 of the drawings represents a top View of the securer for nutsplaced at a short distance from each other; Fig. 2, a side view of thesame; Fig. 3, a top View of another form of the securer for nuts havinga greater space between them; Fig. 4:, a side view of the same, and Fig.5 the nut-securer applied to a fish-joint of a rail.

The nut-securer consists of a plate (1 on which the catch in the form ofa resilient steel bar 7) or the like is fastened in a piece f,

screw-nut (Z, thus securing it. To liberate a nut held fast in thismanner, a pin 8 in the plate under the steel bar 7) is turned by meansof a key or the like and the bar 6 is raised.

What I claim as my invention, and desire to secure by Letters Patent, is

A nut-lock consisting of an ordinary screwbolt and a nut havingprojecting teeth at the base of the sidesurfaces, of a plate aperforated to register with the holes in the fish-plate and rail ends,of a spring I) having one end secured to said plate a and the other endadapted to engage the teeth of the nut, and of a revoluble pin .9,turning in holes of plate a, said pin having a flat part to allow of thespring engaging the teeth, and having a round part to hold said springout of engagement with the teeth, substantially as described.

In testimony whereof I affix my signature.

FRANS VAN THIEL.
